Abstract

PURPOSE: To perform hardening of photopolymerized composition efficiently in a short time by using a reflection mirror which effectively irradiate ultraviolet rays to the surface of the substrate to be painted in hardening the stereoscopic object coated with the photopolymerization composition by irradiating ultraviolet rays.
CONSTITUTION: Photopolymerizable composition is coated on the bottom surface 9, inside surface 10, the surface of projection 11 and outside surface 12 of a stereoscopic object such as a vessel provided with the projection in the inside, and is irradiated with ultraviolet rays L, whereby it is set. In this case, reflection mirrors 10", 11", 12" are disposed on the inside and outside of the stereoscopic object and while the stereoscopic object is being rotated, the ultraviolet rays L are irradiated from above, and are reflected by the reflection mirrors so that the ultraviolet rays are irradiated at angle of incidence of ≤60° with respect to the coating surface 9, 10, 11, 12. Hardening is accomplished efficiently in a short time by controlling the incident angle of the ultraviolet rays, and the respective painting surfaces are hardened uniformly in the same time.
